Description

Zoom on the Ryobi RY905500

In summary, the Ryobi RY905500 is a portable generator especially useful for:

• RV travellers looking for even more independence
• Homeowners in need of an emergency backup power for their essentials
• Professionals who want to be able to deliver results, even during a power failure

In the following paragraphs, we shall explore the power characteristics, available outlets, portability and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Ryobi RY905500

The Ryobi RY905500 is powered by a 420 cc Ryobi OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 5500W as well as a peak wattage of 6875W.

At a noise rating of 78 dBA (less noisy than a dishwasher), the generator offers the possibility to start the device via Ryobi's EasyStart pull-start mechanism (more information below).

The RY905500 can operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH), due to its fuel capacity of 6 gallons.

The quite high THD (<20%) of the RY905500 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel features the following 5 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI

120/240V 30A (L14-30R) receptacle

Since the RY905500 bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

With its dimensions of L31.5 x W29 x H24 in, the conventional, open frame design of the Ryobi RY905500 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 192 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by a wheel kit and a folding handle, which will ease its displacement, once it is on the floor.

EasyStart Mechanism

Ryobi's 3-step EasyStart mechanism

The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:

1. Put the engine switch on the “ON” position, and place the lever on the “START” position
2. Pull the recoil until the engine runs
3. Let the engine run 15 to 30 seconds and place the lever on the “RUN” position

Features

The RY905500's control panel

To help you monitor the RY905500's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Apart from the typical documentation and a user manual, which lets you start it right away, the Ryobi RY905500 also is packed along with the following accessories: oil and tool kit.

Emissions

The Ryobi RY905500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.

Moreover, it features a spark arrestor, making it usable in forested areas.

Product Video

The Ryobi RY905500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY905500 compare to generators of similar power (between 5000 and 6000 W).

• Since the generator weighs in at a dry weight of 192 lbs, the Ryobi RY905500 belongs in the expected weight range for devices which can produce between 5000 and 6000 rated watts. If weight is your top priority, one of the champions in this power category is the Champion 100519, weighing just 121 pounds.
• Among the generators of a comparable running wattage, this generator with a lowest noise of 78 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 52 dBA.
• As for its autonomy, the RY905500, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Cat RP5500, as it provides around 15 hours.
• The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Standing at an estimated 0.6 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.44 GPH, the Westinghouse WGen5500 is a device you should look out for.
